As I understood it, there was the General List, to which unassigned officers were assigned. Their badge was the "Crosse and Blackwell" Royal coat of arms, but in bronze. The General Service Corps was for unassigned soldiers and the badge was in brass.
In 1985, I completed my collection of the then-current British Army badges by buying a General List badge from our clothing store in Edinburgh. We were a Garrison unit back then, so there were "no questions asked"!
